All of the following are true of standard cell potentials EXCEPT: (Select all that apply.) Select all that apply: A galvanic cell generates electric current spontaneously only if the cell potential is positive. The anode is the species with the greater standard reduction potential. Standard cell potential is dependent on the stoichiometry of the overall reaction. A galvanic cell generates electric current spontaneously only if the cell potential is negative.

you gotta add the following molecules so we can give u an answer

explanation:

50.23 i believe is correct but don't quote me on that.

answer: semi-infinite solid initially at a uniform temperature of 400 ◦c is cooled at its surface by convection. the cooling fluid at a constant temperature of 200 ◦c has a convective coefficient (ha) of 250 w/m2.k. the physical properties of the solid: k = 20 w/m.k and α = 4 * 10-5  m2/s. using δx = 0.04 m and δt = 10 s. write the finite difference equations describing the transient heat transfer of the first five δx and the temperature profile after 30 s.
